title: Risk factors in the treatment of abdominal aortic aneurysms in the endovascular ERA.
abstract: OBJECTIVE
  Endovascular aneurysm repair (EVAR) is a minimally invasive treatment that is becoming standard in abdominal aortic aneurysm treatment. We examine the risk factors of death by comparing the short-term results of abdominal aortic aneurysm by open surgical repair with EVAR.
  
  
  METHODS
  We performed elective abdominal aortic aneurysm treatment on 122 cases during the period from January 2008 to December 2009. Seventy one cases were treated with open surgical repair while 51 cases were treated with EVAR.
  
  
  RESULTS
  Compared to the open surgical repair group, the EVAR group was significantly older and had a higher complication rate and past laparotomy rates. No significant difference in hospital deaths was observed between the two groups. Two deaths with thromboembolism due to shaggy aorta were observed in the EVAR group. Two cases in the open surgical repair group developed postoperative myocardial infarction and one death was observed. Both patients underwent coronary artery treatment using drug eluting stents (DES) prior to surgery.
  
  
  CONCLUSIONS
  Shaggy aorta has a high possibility of causing thromboembolism and EVAR should not be performed unless there is a considerable reason. In cases in which coronary artery treatment is performed with DES in recent days, EVAR is more preferable.
